Earth
1.The Great Wall was made of earth first and rebuilt with bricks during the Ming Dynasty, which is what we see now.
长城原来是用土修筑起来的.到了明代才改建了砖石结构.就是我们现在看到的这样.
2.Some history books said they were, but research says "No". It was considered a religious duty because the people believed that the pharaoh was Sun God living on earth. If his corpse was not preserved, the pharaoh could not enjoy life after death.
原来有些历史书上说他们是被抓去的.但后来的研究表明她们是自愿的.古埃及人相信法老是人世间的太阳神.一旦没有保存好法老的遗体.法老死后就不能享受来世.所以他们把建金字塔看成是自己的责任.
